Jászszentlászló Szennyvíztisztító Telep - Advanced Wastewater Treatment in Dél-Alföld, Hungary

Jászszentlászló Szennyvíztisztító Telep is a municipal wastewater treatment facility located in Jászszentlászló, a town in the Dél-Alföld region of Hungary. The plant serves a population of approximately 2,268 residents, classifying it as a small agglomeration under Hungarian and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. With a designed capacity of 2,585 m³/day and an actual discharge volume of 267.36 m³/day, the facility operates well below its capacity, indicating potential for future growth or seasonal variability. The treated effluent is discharged into local watercourses that ultimately drain into the Tisza River basin, a major tributary of the Danube. This connection to the Danube watershed underscores the plant's role in protecting downstream ecosystems, including the Danube Delta, a region of high ecological importance for aquatic biodiversity and migratory bird species.

The plant discharges into the Tisza River basin, which flows into the Danube River and eventually reaches the Black Sea. This watershed supports diverse aquatic life and serves as a critical migratory corridor for fish and bird species. The advanced treatment level helps reduce nutrient loading, protecting downstream water quality in the ecologically sensitive Danube Delta region.
